Although extremely visible on radar, Sizzlipede's low gait and dark colors are often unnoticed by travelers, and even locals often notice their presence more by an unseasonably hot yet shaded area or a puddle in the snow than from seeing the pokemon themselves. Should one not be paying attention, however, one first realizes there is a Sizzlipede underfoot when its scorching heat burns a hole in their shoe – or worse. Third-degree burns are not unheard of, especially when one does not notice what they are standing on, or tries to walk away only to step on another part of the Sizzlipede. In the worst cases, walking on a Sizzlipede cost unwitting people their feet.

Yet Sizzlipede's heat has, at times, been a boon for humanity. Before central heating, it was common to keep one in the bedroom during the winter, moving one's bed (or, if especially good at commanding them, the pokemon) closer or further away to maintain a comfortable temperature for sleep – a custom still practiced in some older homes which have not been refurbished with modern technology. Some trainers in winter even go so far as to leave their Sizzlipede's pokeball half-open for warmth, and the first humans to explore the poles did likewise.

In warm weather and winter-free areas, Sizzlipede (so long as not stepped on) are paid little mind. But they should not be forgotten. The world's climate is affected by more than axial tilt, latitude, currents, and volcanism. Bug pokemon biomass worldwide vastly exceeds that of all other types save for grass, and many unusually warm portions of this world are heated by their abundant Sizzlipede populations; in one famous catastrophe, a once-tropical region froze after excessive pesticide use.
